This is my #1 fast-dry top coat. Doesn't anyone else out there use this too? It isn't available locally as far as I know, I can only find it through an online nailpolish website or eBay. It's made by the Seche Vite company & has most of the excellent qualities of Seche Vite w/o any of Seche Vite's downfalls - no shrinkage! No peeling off nailpolish in sheets. Lower price (generally around $3 instead of Seche Vite's $5-$10) although since I have to order it online it ends up costing $5-$6 anyway, but it's well worth shipping costs. No premature thickening in the bottle & getting all gummy & stringy. No streaks or color changes on top of some susceptible polish colors. No hazardous B3 chemicals (toluene included). None of all that nasty stuff that turned my love for SV into hate. It's packaged in the same bottle as SV but behaves well & performs very nicely. I've been using this since 2010 when I ditched SV & is still my go-to top coat (though I formerly loved Jessica Brilliance - it has a thinner consistency & is equally hard to find, plus costlier).

Below I copy-&-pasted Invincible's description from the internet: Patented formula allows it to penetrate through the nail lacquer to the base coat forming a single solid coating over the nail plate for a much more durable finish which is guaranteed not to yellow. Invincible is unmatched as a top coat leaving the nail silky feeling, stronger, more durable, absolutely will not chip & creates the highest gloss of any product on the market today. Apply thickly, get a nice bead on the end of the brush, then set softly down on the first nail painted & watch how Invincible flows over the wet nail polish self levels & will not drag or streak the underlying manicure. * Guaranteed non-yellowing* Highest gloss* The fastest drying* Non-chipping* Strengthening* Formaldehyde-Free* Nitrocellulose Free* Toluene Free

Basically seems like the same description & directions as the well-known SV. But for the differences I mentioned above, Invincible is superior IMO (& costs a lot less). It dries virtually as fast as SV, doesn't pull wet polish during application, & remains shiny for the duration of my manicure (I change polish 1-2X per wk). I can generally finish a bottle w/o the need to thin it (over time it thickens just very slightly but remains completely workable w/o using any thinner, though I think you can if you want to). IDK why this item isn't well known & more readily available. Does anybody out there use this also?
